Privacy Policy

Last updated: May 2026

Pregnancy Tools ("we", "us", "our") respects your privacy. This page explains what data we collect, why, and how you can opt out.

Data we collect ourselves

None that identifies you. Our calculators run entirely in your browser — we never see the dates, cycle length, or measurements you enter. Nothing is sent to our server. Nothing is stored unless you choose to (e.g. saving a contraction history locally).

Our web server logs basic technical information (IP address, browser type, page requested, timestamp) for security and abuse-prevention. These logs are kept for up to 30 days and are not used for advertising.

Cookies and analytics

We may use Google Analytics 4 to understand which pages are most useful. GA4 does not run until you accept cookies via the banner. You can withdraw consent at any time by clearing your browser's site data.

Advertising

Advertising slots on this site are served by Google AdSense. AdSense uses cookies and similar technologies to show ads, including ads tailored to your interests. You can opt out of personalized advertising at Google's Ads Settings or visit aboutads.info/choices.

For users in the EEA/UK/Switzerland, our cookie banner asks for consent to ad cookies as required by the GDPR and ePrivacy Directive. Without consent, you'll see only non-personalized ads.

Children

This site is intended for adults. We do not knowingly collect data from anyone under 13.

Your rights

Depending on where you live, you may have the right to access, correct, or delete personal data we hold about you. Since we don't intentionally collect personal data, in most cases there's nothing to access — but you can email hello@pregnancytools.net with any request.

Changes

If we update this policy, we'll change the "Last updated" date above and, for significant changes, post a notice on the homepage.
